Right at the cursor arrow -- along that top row of shingles against
the dormer wall, there is a nail in the shingle that pushed through
the shingle. About straight below that point -- in the master bath on
the 1st floor -- the ceiling is discoloring.

First, make sure there's some flashing under the siding, and out onto
the shingles. Also, check the step flashing going up that wall to the
right of the window in the photo. I await your response. Tom


If it didn't leak before the flashing is likely OK. The popped nail is
enough to cause a minor leak.
